Serological Diagnostics

Comparative investigations of the sensitivity and specificity of the indirect immunoenzyme probe - iELISA and the hemagglutination inhibition test (HI test) in serological diagnostics of the Newcastle disease in poultry were carried out using samples of blood serum taken from non-vaccinated and vaccinated poultry. A total of 14 samples of blood serum from non-vaccinated poultry were examined using the immunoenzyme probe - iELISA, and nine of these were found to be positive to the presence of specific antigen against the Newcastle disease virus, while two samples were suspect, and no presence of specific antibodies was established in three samples. Examinations of 82 samples of blood serum from vaccinated poultry for the presence of specific antibodies against the Newcastle disease virus established their presence in 80 serum samples, while one sample was suspect and one sample was negative. The values of the titer of specific antibodies in blood serum samples of vaccinated and non-vaccinated poultry established using the hemagglutination inhibition test (HI test) ranged from 1:2 to 1:32.

The Relationship

The interrelationships of the cellular receptors and the hemagglutinin inhibitors of a new strain of virus (1233) to members of the mumps-Newcastle disease-influenza group have been investigated. It was found that strain. 1233 does not destroy the receptors or inhibitors of the other group, nor does the latter destroy 1233 receptors or inhibitor. The sole exception to this statement was a moderate destruction of 1233 inhibitor in egg white by Newcastle disease virus. The classification of strain 1233 was discussed in the light of this evidence, evidence which tends to place strain 1233 in a different category from that of any other strain of the MNI group.

Background and Aim: The chicken gut harbors microflora which impacts the health, production performance and immune response against pathogens. Assam local chickens reared under natural conditions are known to possess high immunocompetence which may be attributable to its gut microbiota make-up. This study aimed to investigate the individual effect of two strains of Lactobacillus reuteri PIA16 isolated separately from cecum and jejunum of Assam indigenous chicken on the immunity of broiler chickens against Newcastle disease virus (NDV) when fed singly and in combination with a prebiotic. Materials and Methods: A total of 240 birds (48 per group) were vaccinated with Lasota strain of NDV on the 5th and 21st day of age. Blood samples were collected before and after immunization against ND for the detection of humoral antibody response by hemagglutination inhibition test. The cell-mediated immune (CMI) response was estimated through response to phytohemagglutinin-P (PHA-P) and expressed as web index. Results: A significant influence on the immune response to NDV was observed in all the L. reuteri PIA16 as well as mannan oligosaccharide (MOS) supplemented groups revealing higher antibody titer than the control counterpart. The CMI response revealed a better cutaneous basophilic hypersensitivity response to PHA-P in the treated groups than the control. Conclusion: Enhancement in immunity was perceived in the broilers fed with L. reuteri PIA16 and in combination with MOS due to the stimulation of the host's humoral and CMI response by the probiotics and prebiotics used.
